DYE-SENSITIZED SOLAR CELLS WITH COMPOSITE SEPARATOR AND METHOD FOR FABRICATING THE SAME

摘要

A dye-sensitized solar cell including a composite separator and a method for fabricating the same are disclosed. The dye-sensitized solar cell including the composite separator of the present invention comprises; a light electrode which arrays an oxide layer in which a light sensitive dye is absorbed; a counter electrode which is faced with the light electrode; a first porous polymer layer of a gel type which includes an electrolyte and the composite separator between the light electrode and the counter electrode; a second porous polymer layer of a gel type; and a porous supporting layer of a solid state which is arranged between the first and second polymer layers. Therefore, the present invention improves light conversion efficiency and realizes long-term stability by improving the lifespan of an electron. The present invention improves an interface contact characteristic between a separator and a light electrode or a counter electrode and secures mechanical stability and high ion conductivity. Also, the present invention uses a traditional fabricating process of a dye-sensitized solar cell which applies a liquid electrolyte without the adoption of a separate process, thereby having an economical advantage on process.
